A fast and easy method for water transfer of iron oxide nanoparticle based on the hydrophobic interaction of oleic acid coated nanoparticles with the amphiphilic PAMAM-C12 dendrimer is described. The process may be conveniently performed in water and yields nanoparticles with good size distribution, diameter modulation and high crystallinity. The nanoparticles have been functionalized with gadolinium ions to obtain T1/T2 dual mode contrast agents. Furthermore, the possibility to deliver and release lipophilic drugs was investigated. © 2014 SPIE.

Abstract
A fast and easy method for water transfer of iron oxide nanoparticle based on the hydrophobic interaction of oleic acid coated nanoparticles with the amphiphilic PAMAM-C12 dendrimer is described. The process may be conveniently performed in water and yields nanoparticles with good size distribution, diameter modulation and high crystallinity. The nanoparticles have been functionalized with gadolinium ions to obtain T1/T2 dual mode contrast agents. Furthermore, the possibility to deliver and release lipophilic drugs was investigated. © 2014 SPIE.File in questo prodotto:
